Ovulation time of gilts was controlled by oral treatment with altrenogest (17-allyl-hydroxyestra-4,9,11-trien-3-one) followed by gonadotropic hormone injections. Gilts were laparotomized 42 to 44 h after injection of human chorionic gonadotropin. Spermatozoa were surgically placed into ligated oviducts of gilts after one of the following semen treatments: frozen and thawed in Beltsville thawing...

Some persistent organic pollutants (POPs) have been found in human semen but until this point it was unclear whether polybrominated diphenyl ethers (PBDEs) could be detected in human semen. In this study, PBDEs were found for the first time in human semen samples (n=101) from Taizhou, China. The concentrations of total PBDEs (∑PBDEs) varied from 15.8 to 86.8 pg/g ww (median=31.3 pg/g ww) and 53...

The mobility of pooled turkey sperm following various storage regimens was assessed by objectively measuring the ability of sperm to penetrate a 2% Accudenz [5-(N-2,3-dihydroxypropylacetamido)-2,4,6-tri-iodo-N,N'-bis(2,3-dihydroxypropyl)isophthalamide] solution at 41 C. When semen was diluted with Beltsville poultry semen extender and stored at 5 C with agitation at 150 rpm, sperm mobility decl...
